This option was added so we could remove the sysroot path from the env
when cross-build is used over NFS. Though, the implementation wasn't complete
and went unnoticed.
This moves the sysroot path removal into the helper that prepends env so
that no more env get forgotten. This notably fixes the PATH environment.
This means we can use some newer features and get rid of some
boilerplate code using the G_DECLARE_* macros.
As discussed on IRC, 2.44 is old enough by now to start depending on it.
When using hotdoc, one can build the documentation for a single
subproject (eg. the GL plugins). In that case, hotdoc will look
up links in devhelp indexes available in standard locations.
To make sure this case works, we thus need to add the path to
our devhelp index to XDG_DATA_DIRS. This also means when running
devhelp from inside the environment, the devhelp books produced
by hotdoc will now show up.
This is useful to check that a build didn't result in changes in the
code/generated files
This will be used to check that the plugins documentation cache file is
properly commited, and that necessary workaround for particular case
are adopted.
To build the documentation, we are maintaining a 'standardise' `plugins`
variable accross all modules to list all plugins and generate
documentation for them.
This is also used to get the right plugin path when inspecting plugins
for the documentation.
As the data from meson is no longer relative path, it is not longer
possible to move gst-build around and run gst-uninstalled.py. This broke
cross-compilation usage, where you build on a host and run over NFS on
target. This adds an option to tell the script to strip off the host path
to the sysroot.
When relying on a system-wide libnice, we end up not building
the nice elements, which means we can't use them, and by extension
webrtcbin, in the uninstalled environment.
This also introduces a way to avoid checking the version of
a given subproject, and makes use of it for libnice and pygobject,
which only passed the version check by chance, as its current
major version is 3.
This is needed for using the qmlgl out of the box inside
gst-uninstalled. Of course this won't work if the user is using
a native file to specify the path to `qmake`.
... depending on detected shell program. For instance,
if the nearest ancestor process is PowerShell, run uninstalled
environment via PowerShell. Otherwise, $COMSPEC (most likely cmd.exe)
will be used.
When using a custom prompt the automatic override may not look good, so
provide a mechanism to disable it.
Document that the user will have to use GST_ENV manually when setting
the prompt to have a visual indicator of the gst-uninstalled
environment.
Use an array instead of a dict to make sure we iterate over
the list of subprojects in the right order, which is first
GStreamer core, then gst-plugins-base, then other things.
Without this subprojects might get configured in random order,
in which case gstreamer or gst-plugins-base libs might get picked
up via pkg-config if they are also available installed, instead of
being picked up from the subproject. This breaks all kinds of
assumptions in gst-build and will likely have strange effects
and/or lead to build failures such as
subprojects/gst-plugins-good/tests/check/meson.build:144:2:
ERROR: 'gstreamer-plugins-base-1.0' is not a pkgconfig dependency
Starting with Meson 0.50, meson instrospect --targets uses a list
for the filename and install_filenames of each target. Handle both
lists and strings.
